To all whom t may concern.'

Be it known that l, HOWARD A. SELAH, a citizen of the United States, residing in the city of Newark, county of Essex, and State of New Jersey, have invented certain new and useful improvements in Universal Clamping-Brackets, of which the following is a full, clear, and exact description.

1n my prior patent application for alternating current rectiiiers, Ser. No. 851,511 tiled July 17th, 1914, have shown a switch-board with certain parts of the mechanism "mounted thereon. ln practice, the switch-board is made of a slab of slate of considerable size, and upon it are mounted the several elements of the rectifier. The board is ordinarily supported some ,distance from the floor upon upright, tubular standards, and my present invention relates to i brackets for securing the slate switch-board to these upright, tubular standards; but 1 find the same-structure is well adapted to support thel heavier parts of the mechanism,-as for example the motor and the auto-transformer.

While the improved bracket, as above in-v dicated, is primarily designed for the purposes specified, yet it has a wider range of uses and is susceptible of many modifications to adapt it to the diEerent conditions met in not only the electrical `ield, but also inother relations, and 1 therefore do not desire to beA understood as confining the bracket support solely to the purposes hereinafter described, inasmuch as such uses are merely illustrative.

In the drawings Figure 1, is a plan view of the bracket support. Fig. 2, is a side elevation of they same. Fig. 3, isa side elevation of a switch-board supported upon the vertical tubular standards by means of the universal clamping bracket, showing also how'said bracket is utilized for securing lateral braces to the standard. Fig. 4, illustrates in plan a slight modification of the clamping bracket; and Fig. 5, illustratesa side elevation of the same showing the switch-board partly in section.

Similar letters of reference refer to like parts throughout the specification and drawings.

The clamping bracket consists primarily of the two clamping membersl and 2 respectively, and the clamping bolt 3. The clamping member 1 is provided with the apertured lug et, to receive the bolt 3, and at its opposite extremity it has the substantially radial extension 5, projecting to a sufiicient distance to engage the hook 6, upon the extended end of the clamping member 2.

'The latter member is provided .with the apertured lug 7, which also receives the clamping bolt 3. Washers 8, are located beneath the head of the bolt 3, and its nut,.

at 12, to receive a stud bolt 13. ln order to provide an extended bearing ace adja cent to the bolt 13, mayprovide a lateral extension upon the boss 1l, as shown at 14;.

the outer end of the bolt 13, receives the ory namental cap nut 15.

`When in use upon the upright tubular standard 16, the clamping members 1 and 2 are adjusted tc'position and the nut of the bolt 3, is screwed home so that the bracket is irmly clamped to the upright standard 16, with the stiid bolt 13l in position to enter apertures 'in the switch-board 17, provided therefor. i/lfhen in place, the ornamental cap nuts 15, are screwed upon the projecting ends of the stud bolts 13, and the switchboard is' firmly held in position. W hen the nut upon the bolt 3, is screwed home against the apertured lug 4, the clamping e'ect upon the tubular standard 16, is such that it is impossible with ordinary means to slide the clamping bracket along said standard. The braces 9, held between the apertured lugs 4 and 7, by the bolt 3, may be either extended diagonally to the i'loor upon which the standards 16 are mounted, where the opposite ends are held in foot plates. 18, in any usual or preferred manner, or 1n case the switch-board is located a .distance from a wall, the brace 9 may extend horizontally and the opposite end secured to the wall through the foot plates 18. Vthen thus braced, the upright standards 16, are capable of supporting all of the parts of my l improved rectifier above referred to, inciuding the switch-board, the motor, and the auto-transformer.

l haveno-t deemed it necessary to further' illustrate the structureof my-former patent application inasmuch as tforms' no part of my present invention.

Insome cases it is necessary to packthe parts of a rectifier in separate boxes or crates,jfor eXample,the standardsmay be boxed ready for erection, and the switchboard carrying all of the delicate instruments necessary to the rectifier, is separately crated. Under such conditions l may provide va modified formof'bracket whereby the switch-board maybe readily hung upon the upright standards 16, through the me-v dum of the clampingibracket. This modi-y fied form is shown 'clearly'in Figs. 4 and 5,

yet the operative parts of the structure are substantially the same as illustrated in the `other figures, the difference residing merely in the enlargement of the boss 11, and the provision of a vertical aperture 19, through said boss. The switch-board 17, in such case, is provided with an L-shaped bolt'20, said bolt passing through lthe switch-board l 17 ,fas clearly illustrated in Figs. 4 and 5,'

and is secured in place4 through the medium of the ornamentalrcap nut 15, and the collar 21, which is integral witth .the bolt 20. The rear end of the bolt 20, is bent downwardly I A as at22, to form a pintle to enter the aper-v vture 19, in the clampingmember 2. It will thus be-seen that with the parts of the upvright standard 16, assembled, and the clamping member adjusted to propelyposi tion, it is only necessary .to hook the bolt l. .40 20 into the apertures 19, of the' clamping K, the standards; .and .the switch-board maybe bracket, to mount the switch-board 17 upon -upon one of said 'clamping members for amener members'having a hook at one end for engagement with aprojection upon the cor/re'- sponding end of -the other member, means at` the opposite ends of said members-for drawing said clamping members together to clamp an object therebetween, means supporting another object thereon, and a brace secured by said means to said clamping members.

2. In a clamping bracket, the combination of a pair of clamping members, one of said 'members having a hook at one end for engagement with a projection upon the corresponding end of the other member, the op' posite ends of said members being provided with apertures, a screw bolt passing through said apertures to draw said members together to clamp said members to a support,

means upon one of said clamping'members for supporting another object thereon, and

a brace located upon said bolt between said clamping members.4 s

ln testimony whereof, I have hereunto l set my hand this 22d day of November, 1914;. i
